I am a fourth-year PhD student in the College of Engineering at Northeastern University. I am a member of MAGICS Lab (Multi AGent Intelligent Complex Systems), and my advisor is Babak Heydari.

My research interest is at the intersection of Applied Artificial Intelligence and Social Science. Currently, my focus is on analyzing the causal effect of system-level treatments on users' interaction patterns in digital platforms: who is more affected by ChatGPT, what type of users, and why?

About Me

Academic Background:

Experiences:

  • AI Researcher: Harvard Medical School – Nezami Lab. I completed my 2025 summer internship there and am wrapping up two applied AI in healthcare papers.
  • Graduate Teaching Assistant: Engineering Management master’s-level course at Northeastern’s College of Engineering.
  • Systems and Processes Analyst: Before starting my PhD and moving to the US, I worked in industry for four years, gaining experience in process mining, data mining, dashboard design, product design, project management, and cross-functional collaboration with product managers and software development teams.

Research Interests

My research focuses on the intersection of AI / statistics and social science. I am particularly interested in:

  • Modeling / forecasting user behaviors and adverse system outcomes: Generative AI (Transformers, CNNs, RNNs, LSTM, GRU, LLMs) and classic ML (XGBoost, KNN, Naive Bayes, regression, …).
  • Estimating the causal effect of system-level treatments: Using causal inference (regression discontinuity, difference-in-differences, event study, synthetic control models).
